scope of the invention .will' be more fully understood from the following description takenin connection with the accompanying drawings forming part hereof and in which:

Figure 1, is a View in elevation of the improved dyeing apparatus of the invention,

Fig. 2,. 1s a top or plan view, upon a reduced scale, of the dye tub or tank shown in 1 1g. 1, Fig. 3, is a view in vertical secition taken upon the line 3- -3 of Fig. 2, Fig.

14:, is a fragmentary view in section, drawn to an enlarged scale, and lllustrating details of construction shown in Fig. 3, and

Fig. 5, is a i'agmentary view, inplan, of one of the removable perforated plates shown in Figs. 2, 3, andelz.

In the drawings there is disclosed a speciiic embodiment of the invention construct- ;ed in accordance with the mode best known to me at this time for practising-the invention. and general arrangement of parts may be varied to accomplishthe same purposes and I wish it understood that such variations :and arrangement of parts come within the scope of the present invention. The tub or tank for containing the goods to be dyed, is designated 10, and for illustrative purposes is shown as comprising a wooden structure divided into compartments 11., and 12, of different sizes by means of a vertical partition 13. The compartment 11, which is relatively large and. is a goods receiving chamber is provided upon its side walls with tion, to form shelves, see Fig. 2. Each plate is provided at its opposite ends with a temporary securing medium shown in the.

drawings, as being a shiftable bolt 16, which bolts are adapted to be accommodated by apertures 17, inthe side walls of the tub or tank 10, see Fig.4 By such construction, the plates 15, may be readily fitted and tem:

Obviously, details of construction porarily secured in place in, the compartment 11, of the tub or tank 10, and as readily removedtherefrom. The plates 15, are also preferably provided with means whereby the same maybe readily lifted from said compartment. As shown, hand grips 18, secured above or adjacent the bolts 16, may be conveniently used. Within the compartment 11, of the tub or tank 10, beneath the lowermost shelf and resting uponthe bottom of the tank is a union joint 19, branching from which area plurality of short pipe sections 20, slotted as at 21., to form a liquid distributer. Theunion joint 19, connects with a pipe 22, which extends up through the bottom of the tank 10, for a purpose to be presently described. The tub or tank 10, conveniently at one side thereof, is provided with a waste water overflow conduit 23, having communication'as at 24, see Figs. 2, and 3, with the top ofthe compartment or chamber 11, which conduit 23,

may lead to a sewer connection or' other de-' sired point. This conduit 23, is utilized when goods are being washed after the dyeing process, at which time a movable gate 25, shown in the drawings as having hinged relation with the top of the partition 13, is used in conjunction with said conduit, as will hereinafterbe described.

A description will now be given of the means utilized for circulating dye first upwardly through the perforated plates 15, and then reversely downwardly through said plates.

Locatedbetween the tub or tank 10, and the stock liquor or dye reservoir 26, is a centrifugal pump27, operable by any suitable medium. As shown in the drawings,the drivingshaft 28, of the centrifugal pump is provided with fast and loose pulleys 29, and 30, belt 31, being present for driving purposes. Leading from the inlet end 32, of the pump 27 is a horizontal pipe 33, connecting with the compartment 12, of the tank 10, which compartment is relatively small. and may be; termed an auxilary chamber. Leading from the outlet end 34, of said pump is a vertical pipe 35, which connects with a horizontal pipe, the branch 36, of which has a valve 44, and leads to the top of the stock liquor or dye reservoir 26, and the branch 37 of which terminates in .relatively vertical sub-branches 38, and 39. Of these sub-branches 38, and 39, pipe 38, connects with the pipe 33, and pipe 39, connects with the pipe 22, which pipe 22, in turn, is branchedfrom the pipe 33, and connects .with the union joint 19, within the compartment 11, asherei-nbefore described. At the juncture point of the-branches 37, 38-, and 39, a three-way valve 40, is present and at the juncture point of the pipes 22, and 33, a three-way valve 41, is present. Leading from the reservoir 26, and connecting with the pipe 33, adjacent'the inlet end of the pump 27, is a pipe 42, having a valve 43. It will. thus be seen that the three-way valve 41, as shown in Fig. 1, is located at a point upon the pipe 33, intermediate of the pipe 42, and the pipes 38, and39. Leading from the branch pipe 36, at a point intermediate the valve 44, and the outlet connection 35, of the pump 27, is a waste water discharge pipe 45, provided with a valve 46. This pipe 45, may lead to a sewer connection or other suitable point.

The goods to be dyed being in position,

upon the shelves within the compartment 11, the centrifugal pump 27, is operated and the various valved connections adjusted, so

that stock liquor or dye from the reservoir 26, is drawn through the pipe-42,. to and through the pump 27, and forcedout through the outlet connection 35, to branch 39, to and through pipe 22, and into the compartment 11, of the tub or tank 10, at which point said dye is distributed evenly over the base area of compartmentll, and is forced upwardly through the superimposed, perforated, plates 15, andthrough the goods contained thereon. operation the overflow stock liquor or dye passes over the top of the partition 13, into pipe 37, thence downwardly through pipe" During; this the auxiliary compartment '12, from which 1 point it passes back to the inlet end 32, of the eentrlfugal pump 27. By this arrangement of parts when the compartment 11,

has been sufliciently filled, the valve 43', of

the pipe 42, may be closed and a continuous cycle of liquid dye be circulated through the goods being dyed, steam being injected" into the auxiliary compartment 12, of the tank 10, by means of the pipe 47, for keeping the liquid dye heated during the dyeing operation. After the stock liquor or dye has. thus been circulated for a suflicient length of time, the three-way valves40, and 41, and the other valves are so adjusted that the dye in the compartment vll, of the tank .10, is caused to be drawn or sucked through pipe 22, to pipe 33, through the pump 27, and then forced out through the connection 35, to the branch pipev 37, and fromsthence through pipes 38,. and 33, to the compartment 12, of the tub or tank 10, and over the top of the partition 13, to the compartment 11, and is then caused. to be drawn or sucked down through the "apertured plates to the pipe 22, andtothe pump 27, thus completing a continuous cycle of'dye and in effect recirculating the forced through the tub or tank in an op.- posite vertical direction. This last operation being continued untilthe goods are thoroughly dyed, the three-way valve .40, is adj usted to. shut off pipes the other valves adjusted within the tub or tank, is drained out dye previously 38, and 39, and so that the dye The oods are now ready to be washed. For this purpose the valve of the watein supply pipe 48, is opened thereby permitting clean water to empty into the auxiliary.

compartment 12, of the tub ortank 10, from which point it is drawn or sucked by the pump 27, through pipe 33, and exhausted through ipes 35,. 37, 39, and 22, to the bottom of t e tub or tank, the valves 40, 43, and 44, having been previously regulated to permit of such circulation. The gate 25,

of partition 13, is now lifted to the position shown; in Fig. 3, in which position it may be retained by means of shiftable bolts 49, similar to those disclosed in Fig. 4. The gate 25, in elevated position extends the partition 13, so that the top thereof is above the inlet opening 24, of the waste water conduit 23. Thus the conduit 23, will readily drain off dirty water and scum at the tank top whereby clean water is constantly supplied to the tub or tank 10, and the dirty water drained ofi'. \Vhen the goods are sufficiently washed, the valve 46, of the pipe 45, is opened, the three-way valve 40, closed and the water within the tank 10, is exhausted through the pipes 22, and 33, pump 27, pipe 35, branch, pipe 36, and pipe 45, to a sewer connection or other suitable point. The goods upon the shelves within compartment 11, thus dyed and washed may now be removed and in this connection, it is to be noted that the commercial value thereof is enhanced by reason ofqthe fact that the goods are uniformly and evenly dyed; the texture of the fabric is not roughened; the goods themselves are not rumpled and be cause they are thoroughly and efliciently washed. It may be remarked that theseresults are attained chiefly because the goods are retained between the shelves in relatively fixed position and the dye and water forced therethroughin contradistinction to having the goods, whirled or; circulated through the dye and water.
